Steve Loughran commented on MAPREDUCE-679:
------------------------------------------
Same comments as for HDFS-453
# a JSPX page may make it easier for generating XML; especially for ensuring
there isn't any whitespace ahead of the xml header declaration, or bad xml
inside it.
# caching needs to be turned off here and in all JSP pages as per HDFS-91
# your {{generateJobTable}} code can/should iterate as {{for(JobInProgress
job:jobs) instead of Object
Can you attach some example XML, I'd like to look at it a bit more too, see how
well it would for for XSL/Xpath navigation

> In HADOOP-4559, a general REST API for reporting metrics was proposed but
> work seems to have stalled. In the interim, we have a simple XML translation
> of the existing JobTracker status page which provides the same metrics
> (including the tables of running/completed/failed jobs) as the human-readable
> page. This is a relatively lightweight addition to provide some
> machine-understandable metrics reporting.
